24 V Server Fan for 120 mm Mounts

The AFB1224SHE -8L2B is a square frame case fan built for 24 V DC operation in server and industrial chassis. It draws 0.75 A and fits standard 120 mm mounting holes with a 38 mm thickness. The three-wire lead provides power, ground and a tachometer signal for speed monitoring. This unit suits technicians maintaining rack equipment that requires 24 V cooling.

24 V Supply Required — No PWM Control

The fan runs only from a 24 V source; it cannot be powered from common 12 V motherboard headers or 5 V USB ports. Speed is governed by voltage level, not by a fourth-wire PWM signal, so automatic low-noise curves are not available. Builders needing variable speed via PWM or 12 V compatibility should select a different model.

Highlights

  • 24 V DC input powers server-grade cooling reliably
  • 120 mm square frame fits standard 120x120 mm mounting holes
  • 38 mm thick profile delivers high static pressure airflow
  • 3-wire connection enables speed monitoring via tachometer signal

Questions about this item

Is the 120 mm frame the right fit for my 120 mm mounting holes?

Yes, the 120 mm square frame matches standard 120 mm mounting holes; the 38 mm thickness adds depth, so confirm your chassis clearance before fitting.

What does the 0.75 A draw at 24 V mean for my server's fan header?

At 24 V the fan pulls 0.75 A; verify your header can supply that current and that the third wire provides the tachometer signal your board expects.
